| 摘 要： | 针对电机实验站对永磁同步电机实验电源系统新的控制要求，研究了MW级永磁同步电机无速度传感器矢量控制方法，提出了一种基于模型参考自适应的速度辨识方法。该方法仅用q轴磁链误差信号构建自适应率辨识转速信息。首先通过Matlab仿真证明了该方法的有效性，然后进行了半直驱隐极式永磁同步风力发电机对拖实验，结果证明该方法能较好地辨识电机转速。

| Abstract: | For the new control demands of permanent magnet synchronous motor(PMSM) experimental power supply system,speed sensorless vector control method of MW Turbine PMSM was researched,and a new speed estimation method based on model reference adaptive system(MRAS) was proposed.In the method,the q-axis flux error signal was used to construct adaptive rate and estimate the speed.First by Matlab simulation the validity of the method was proved,then the test of two half-direct permanent magnet synchronous generators towed each other was made.The result of the experiment shows that the method has a good speed estimation effect. |
